What is Personal Information?

‘Personal information’ refers to any data that can identify you as an individual. This policy outlines how we handle personal information when you use our AI-powered platform designed to assist private and public schools with automated math grading, feedback, and administrative support.

We are not responsible for the privacy practices of third-party websites or services that we do not own or control.

Sensitive information is used only for delivering our services and is not used for any other purposes. All data uploaded to our platform remains your property, and we act solely as a data processor.

Cloud-Based Data Storage and Management

We use secure, cloud-based storage for user-uploaded files. Our platform ensures:
